Anti-recombinogenic and convertible co-mutagenic effects of (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVDU) and other 5-substituted pyrimidine nucleoside analogs in S. cerevisiae MP1.

Abstract excerpt

In experiments using yeast, without addition of an external metabolic activation system, (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVDU) was co-mutagenic and showed an insignificant anti-recombinogenic effect in combination with triethylene melamine (TEM). In the presence of activating S9-mix, the anti-recombinogenicity and co-mutagenicity could clearly be seen. At higher concentrations the co-mutagenic effect was...
